To unlock a bonus stage after any regular stage, finish the stage with a good score (near 1,000 points). You will be brought to Chop Chop Master Onion Head who gives you a fun, yet somewhat repetitious bonus game between the end of the stage you just finished and returning to the stage selection map.

If you set the time to 10:30 p.m. it will be dark outside.
